The current research are specializing in prednisolone, used within the remedy of Rheumatoid Arthritis, and metformin, used within the remedy of kind 2 Diabetes. With biobanking and the obtainment of knowledgeable consent for future, but unspecified analysis, the protocol opens for long-term comply with up of treatment results on breastfeeding infants.

Girls are recruited by way of a community of medical centres in Sweden, and the samples are saved for future analysis in a community of breast milk biobanks managed by BBMRI-ERIC. In response to Mats G. Hansson, this ensures the examine is an element of a bigger European infrastructure, making future analysis attainable.

The just-published protocol was developed inside the massive European collaboration framework ConcePTION, and describes how samples are collected and analyzed.
